I am an historian of contemporary Germany with a diverse range of research interests from transnational histories of sexuality, everyday life and visual culture to the history of populism and authoritarianism, especially as it evolves across platforms in social media and memory. I have published books and articles about same-sex sexuality in post-1945 Germany, memory activism in social media, and history and photography. My newest book, Queer Life After Fascism (Duke University Press 2023) takes up the question of respectability politics in queer and trans* organizing, art, and remembrance in the late 20th century Germany and argues for kinship as a category of historical analysis. Current projects include a monograph on the history of social media and post-Holocaust memory, a transnational study of erotic photography during the Sexual Revolution, and a critical social media analysis of historical misremembering as a form of misinformation in the contemporary populist moment.

I am one of the organizers of the Holocaust Education Foundation's bi-annual Lessons and Legacies conference, a series editor of Bloomsbury UK's Modern German History series, member of the Circle of Friends of the Schwules Museum* Berlin, and advisory board member of the Berlin Program for European and German Studies with the Free University of Berlin. I also sit on the advisory board of the journals German History, German Politics and Society, and de Gruyter's new book series Transnational Queer Histories. Alongside my academic writing, I undertake collaborative digital projects like the New Fascism Syllabus (www.NewFascismSyllabus.com) and the German Studies Collaboratory (www.GermanStudiesCollaboratory.org). 

My work has been supported by a variety of grant agencies and institutions including the the Department of Canadian Heritage, Social Sciences Humanities Research Council of Canada, the Social Science Research Council (US), the United States Holocaust Memorial Museum, the German Academic Exchange Service, the German Historical Institute, the Humboldt University of Berlin, the Berlin Program of the Free University of Berlin, Sciences Po and the Fondation Maison de Sciences de l'Homme.  My writing has been published in  The Washington Post,The Guardian, the National Post, the Globe and Mail, andThe Conversation and in 2016 I was elected to the Royal Society of Canada's College of New Scholars.
